Is this sharp?

There is some concern on the web that the X100s is not sharp at f2 when focused closer than about 10 feet. I don't think there is a problem, because this picture of my son, taken close at f2, seems sharp to me even at 100%. Naturally the depth of field is shallow.

My son about to catch a train to return to university after the Easter break. Taken at f2.0 on my Fuji X100s

I'd be interested to know whether others find this picture is as sharp as they would expect.
